At the end of the day, the basic moral tenets of the christian faith can be found in every other faith, this aspect of the christian faith is the least unique IMO. "Love thy neigbor," being able to let things go, and helping the less fortunate are also in fact Buddhist rhetoric. Mr. Rodgers leaned on his faith because that's the philosophy he knew and understood how to use examples from. If his mother raised him with Eastern philosophy instead of scripture, he probably would have put up words from the Buddha which convey a similar message instead of that bible verse.
